IMPROVEMENT IN WINDOW-SASHES.

Specification forming part of Letters Patent No. 120,267, dated October 24, 1871.

To all whom t may concern:

Be it known that I, JOHN GRovEs, of the city, county, and State of New York, have invented a Anew and useful Improvement in Vindow- Sash a double and reversible catch, which locks the sash to the `stileand the stile to the frame.

Figure l of drawing is a front v iew, partly in section, of a sash with my improved fastening.v Fig. 2 isa vertical section of the same.

A is the window-sash; B B, the stiles; and K, the stile-frame. The sash A is pivotcd, at the points C C, to the stile B in the usual way, and fitted snugly thereiiito against a suitable iiange or stop. g E is` my improved catch-bar, having studs F respectively on each side of its free end and pivoted to stile B. G are slotted plates on the top of sash, and I slotted plates on the stile- `rame which receive the studs of the catch-bar.

By this construction it will be perceived that one double-studded and reversible catch on each side ofthe sash does all the locking.

Having thus described all that is necessary to a full understanding of my invention, what I esteem to be new is The double-studded and reversible catch E F H pivoted to the stile B, and operating to lock the sash to the stile and the stile to the frame, as set forth.
